Abstract: The experiment was conducted employing Randomized Block Design (RBD) with four replications, 100 accessions per replication and 9 plants per accession at a spacing of 3 metre x 3 metre. The main aim of the experiment was to determine the fruit yield and vegetative traits of 100 accessions, to estimate the genetic variability and heritability and to study the relationship among these traits. The performance of all traits showed highly significant variations. Broad sense heritabilities for height, collar diameter, the diameter of the first branch, number of branches and survivability was 0.23, 0.17, 0.22, 0.25 and 0.20 with a genetic gain of 14.36, 8.08, 11.72, 15.74 and 13.37 respectively. The number of branches was most important traits with maximum genotypic and phenotypic coefficient of variations of 15.44% and 30.77%, respectively for yielding point of view. Accession IC 468907 maintained 1st ranks in height, collar diameter, number of branches and fruit production among all accessions. Accessions IC 468907, IC 468919, IC 471353, IC 468909, IC 568552, IC 566538 and IC 471343 were the best performers for all traits including fruit production. The assessment of different accessions indicated large genetic improvement possibilities in Jatropha curcas.
